Eternal life was opened to us by the Paschal Mystery of Christ and faith is the way to reach it. This is what what emerges from Jesus' words to Nicodemus in the Gospel of the Evangelist John: “And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up, that whoever believes in him may have eternal life" (Jn 3:14-15). The explicit reference to the episode narrated in the book of Numbers (21:1-9) highlights the saving force of faith in the divine word. During the Exodus, the Hebrew people rebelled against Moses and God and were punished by the plague of fiery serpents. Moses asked for forgiveness and God, accepting the repentance of the Israelites, ordered him to “make a fiery serpent, and set it on a pole; and every one who is bitten, when he sees it, shall live”. And so it happened. Jesus, in his conversation with Nicodemus, revealed a more profound significance of this event of salvation, referring it to his own death and Resurrection: the Son of Man must be lifted on the wood of the Cross so that whoever believes in him may have life. St John sees precisely in the mystery of the Cross the moment in which the real glory of Jesus is revealed, the glory of a love that gives itself totally in the passion and death. Thus, paradoxically, from a sign of condemnation, death and failure, the Cross becomes a sign of redemption, life and victory, through faith, the fruits of salvation can be gathered.
